Girl-on-girl? FucM.

Contender for Appropriately Named Gene of the Year?

A GENE has been discovered that appears to dictate the sexual preferences of female mice. Delete the gene and the modified mice reject the advances of the males and attempt to mate with other females instead.

While it is impossible to say whether the finding has any relevance for human sexuality, it provides a clue as to how sexuality develops in mammals.

Chankyu Park and colleagues at the Korea Advanced Institute of Science and Technology in Daejon, South Korea, deleted the FucM gene in mouse embryos to see what effect it would have on behaviour.

Female mice lacking the gene avoided the advances of males, stopped sniffing male urine and attempted to mate with other females, though their ability to have pups was unaffected (BMC Genetics, DOI: 10.1186/1471-2156-11-62).

I hope we don't get a bunch of assholes claiming 'sexual preference isn't a choice - it's genetic'.

I have heard so much of that it makes my ears hurt. Sexuality is both, as far as I can tell. Interesting what they have discovered, though.
